    摘要: Magnetic RAM cells have split sub-digit lines surrounded by cladding layers and methods of fabricating the same are provided. The magnetic RAM cells include first and second sub-digit lines formed over a semiconductor substrate. Only a bottom surface and an outer sidewall of the first sub-digit line are covered with a first cladding layer pattern. In addition, only a bottom surface and an outer sidewall of the second sub-digit line are covered with a second cladding layer pattern. The outer sidewall of the first sub-digit line is located distal from the second sub-digit line and the outer sidewall of the second sub-digit line is located distal the first sub-digit line. Methods of fabricating the magnetic RAM cells are also provided.

    摘要: A phase-change random-access memory (PRAM) device includes a chalcogenide element, the chalcogenide element comprising a material which can assume a crystalline state or an amorphous state upon application of a heating current. A first contact is connected to a first region of the chalcogenide element and has a first cross-sectional area. A second contact is connected to a second region of the chalcogenide element and having a second cross-sectional area. A first programmable volume of the chalcogenide material is defined in the first region of the chalcogenide element, a state of the first programmable volume being programmable according to a resistance associated with the first contact. A second programmable volume of the chalcogenide material is defined in the second region of the chalcogenide element, a state of the second programmable volume being programmable according to a second resistance associated with the second contact.
